Keep all metallic objects off the top of the
batteries, which may cause a short circuit.
Replace any worn or damaged wires.
Never add acid to the batteries, only distilled
water. Always keep the battery caps on, except
when adding water or taking hydrometer readings.
Check the electrolyte level in each battery cell
before and after charging, and after every
50 hours of operation. Do not charge the batteries
unless the fluid is slightly above the battery plates.
If needed, add just enough distilled water to cover
the plates. Never add acid to the batteries. Do not
overfill. Always keep the battery caps on, except
when adding water or taking hydrometer readings.
Measuring the specific gravity, using a
hydrometer , is a way to determine the charge level
and condition of the batteries. If one or more of
the battery cells test lower than the other battery
cells (0.050 or more), the cell is damaged,
shorted, or is about to fail.
NOTE: Do not take readings immediately after
adding distilled water. If the water and acid are not
thoroughly mixed, the readings may not be
accurate. Check the hydrometer readings against
the following chart to determine the remaining
battery charge level:
SPECIFIC GRAVITY
at 27_ C(80_F)
BATTERY
CHARGE
1.265 100% Charged
1.223 75% Charged
1.185 50% Charged
1.148 25% Charged
1.110 Discharged
NOTE: If the readings are taken when the battery
electrolyte is any temperature other than 27_ C,
the reading must be temperature corrected. Add
or subtract to the specific gravity reading 0.004,
4 points, for each 6_ C above or below 27_C.
